Castle of Black Iron

The powerful turbulent flow of four elements came and went fast and fiercely.

In less than half a minute, all the turbulent flows of elements had disappeared. As a result, Zhang Tie and the other elders of Dragon Emperor Immortal Palace reappeared in the sky above the camp of Dragon Teeth Army. They were still surrounded by the rigorous Dragon Teeth Army. However, Xia Yangming and Shi Zhongyu had already disappeared.

Zhang Tie advanced to the ground at once.

Just now, Xia Yangming and Shi Zhongyu drilled into the ground just right below the viewing platform. However, there was not any hole on the ground at all.

The other elders also landed beside Zhang Tie as they gazed at the earth with complex looks. Long Jiu Tian was infuriated as he fiercely punched at the ground, causing a huge pit.

“What method did Xia Yangming and Shi Zhongyu use just now?” Zhang Tie asked the other elders in a muffled voice.

“They were previously earth-level rarities of Earth-Treasures Department of Dragon Emperor Immortal Palace. Shi Zhongyu’s sword is called Heavenly-Separation Sword while Xia Yangming’s item is Earth-River Vehicle…”

“I’ve never heard about that?”

“Because the two items have already lost in an accident over 7 decades ago!” Luo Yunshang watched the pit with deep fury and unwillingness. The other elders also revealed complex expressions.

“Can you make it clear?”

“The two rarities were gained by the former Dragon Emperor from the Mountain Ruins. Previously, the two items were collected in Dragon Emperor’s Pavilion. Later on, as the former Dragon Emperor didn’t come back for so many years and the two rarities were too eye-catching, elders determined to transfer the two rarities into a secret warehouse of Earth-Treasures Department through discussion for the sake of safety. A team of immortal generals was especially responsible for guarding them. Commoners could barely touch them. However, 7 decades ago, Earth-Treasures Department had an accident. The two rarities were stolen away. Besides, all the 60-odd immortal generals who were responsible for guarding the two rarities were killed…”

“Ah? That’s a big accident. But why I haven’t heard about it in Heavenly Square City?” Zhang Tie asked with a frown.

“This event was a big shame for Dragon Emperor Immortal Palace. We all knew that the two rarities were robbed away. However, Dragon Emperor Immortal Palace had almost collapsed. For the sake of the fame of Dragon Emperor Immortal Palace, we kept this accident a secret. We could only investigate it secretly in vain. Over these years, we especially paid attention to the two rarities; however, we never saw anyone use them. We even thought that they had fallen in the hands of demons. Unimaginably, it was Xia Yangming and Shi Zhongyu who robbed them. It seems that the two people have long got evil intents and ambitions…”

“What’re the features of Heavenly-Separation Sword and Earth-River Vehicle?”

“Heavenly-Separation Sword is very powerful and sharp. Within 100,000 m, it could easily tear human-level outfits and one’s protective battle qi. It’s known as the conqueror of human-level outfits and protective battle qi. When the former Dragon Emperor gained Heavenly-Separation Sword, he barely used it because of its strong lethality. Earth-River Vehicle is used to travel into the ground. As long as it’s started, it would be able to traverse freely into the ground even faster than common immortal generals in metal wings. If you don’t block it before it enters the ground, even immortal emperors couldn’t catch up with it. Xia Yangming and Shi Zhongyu might have already traveled tens of thousands of meters into the ground by Earth-River Vehicle…”

‘As long as it enters into the ground, the ground would be the best shield. Also, high-level immortal generals could fly in the sky, nobody could fly into the ground. Even I could only travel a short distance inside the ground by some means. But I could never match the golden secret item.’

Zhang Tie nodded as he listened to Luo Yunshang’s explanation. After that, he took a look at the deep scar on his mace as he felt terrified of Shi Zhongyu’s strike using Heavenly-Separation Sword. “Now that Heavenly-Separation Sword is so powerful, why didn’t Shi Zhongyu kill all of us using it?”

“Although Heavenly-Separation Sword is powerful, it requires enormous battle qi to drive it. The former Dragon Emperor said that even supreme-level immortal generals could barely use it for a long period of time. Average fire immortal generals could barely brandish Heavenly-Separation Sword for 4-5 times. The Grand Dragon Emperor said Heavenly-Separation Sword was suitable for assassination. Instead of being used on the battlefield, it was more suitable for sneak attacks. On many occasions, people who used it should kill their enemy instantly before escaping away…”

“What about Earth-River Vehicle? How to drive it?”

“Earth-River Vehicle should also be driven by battle qi. But it doesn’t need too much battle qi. As long as the driver’s battle qi is not exhausted, he would be able to travel into the ground by Earth-River Vehicle constantly. Given Xia Yangming’s battle strength, he could at least travel for a few days by Earth-River Vehicle, during which period, he could even leave the territory of Dragon Emperor’s Big Domain or lurk somewhere or directly stay underground…”

After checking out the backgrounds of the two rarities, Zhang Tie instantly made a decision as he told those elders, “Xia Yangming and Shi Zhongyu betrayed Dragon Emperor Immortal Palace. They even killed the immortal generals of Dragon Emperor Immortal Palace for the two rarities. Their sins should never be forgiven. We should never let them go. Now that the two people have already exposed their real identities, they must have henchmen in Dragon Emperor Immortal Palace. During this period, elders, please go back to Dragon Emperor City and clean up the two people’s henchmen in Dragon Emperor Immortal Palace so as to stabilize the overall situation facing Dragon Emperor Big Domain in case of other conspiracies of the two people. You could determine everything about Dragon Emperor Immortal Palace through discussion!”

“Ah, where are you going, Your Majesty?”

“Xia Yangming and Shi Zhongyu have already exposed their real identities. As they’re crystal clear about Dragon Emperor Immortal Palace, if not eliminate them, Dragon Emperor Immortal Palace would never be peaceful. Therefore… thank you so much…”

After exchanging a glance with each other, those elders bowed towards Zhang Tie together, saying, “Don’t worry, Your Majesty, we swear to take care of Dragon Emperor Immortal Palace for you…”

Zhang Tie nodded silently. Closely after that, he flew towards northwest after passing the large battle formation of Dragon Teeth Army.

Seeing Zhang Tie off, all the elders thought Zhang Tie was looking for the “old man” to deal with Xia Yangming and Shi Zhongyu. Therefore, they all became reassured. Then, they rushed in the sky at the same time and returned to Dragon Emperor City to clean up the henchmen of Xia Yangming and Shi Zhongyu…
